Event Pokémon

Summary
A Shiny Pokémon, also recognized as alternate coloration or rare coloration, is a specific Pokémon with different coloration to what is usual for its species. It is one of the many differences that a Pokémon can have within its species.

The term "Shiny Pokémon" was first created by fans to refer to the sparkling sound effect and animation made at the start of an encounter with one in the games. Eventually, this term fell into official usage of The Pokémon Company.

Shiny Pokémon can differ in color from their normal counterparts very little or very much.

Some Pokémon have a Shiny coloration only a few shades darker or lighter in color. For example:

However, many Pokémon have a spectacular difference between their normal and Shiny variations. For example:

Gameplay
When a Shiny Pokémon appears in the wild or is sent out of its Poké Ball, stars will briefly surround it and make a pinging sound effect. When viewing a Shiny Pokémon's profile, a red star is indicated on the right bottom corner of the Pokémon.

Shininess is inherent to an individual Pokémon; that is, a Pokémon that starts out Shiny will always be Shiny, and one that is not will never be. Upon evolution, a Pokémon will retain its Shiny status; for example, a Shiny Charmander, if leveled up, will eventually become a Shiny Charmeleon and then a Shiny Charizard, just as a regular Charmander will become a regular Charmeleon and then a regular Charizard.

Shininess is determined by a complicated formula, which results in a probability of 16/65536 or 1/4096 in encountering Shiny Pokémon in the wild or through breeding. This probability can be enhanced by buying the [|Shiny Charm] for R$500 and/or purchasing RO-Powers for R$100 in-game to increase Shiny Rate for 1 hour. If both items are purchased, they will stack, making the shiny rate 1/128.

There are 4 ways to obtain a Shiny Pokémon:
 * Encountering a Wild Pokémon
 * Breeding and hatching a Pokémon
 * Obtaining a Pokémon in-game or from official events
 * Trading Pokémon with other players
